Composite water-proof coiled material and construction method by employing same

Abstract

The invention discloses a composite waterproof coiled material, from top to bottom, in turn including isolating layer, sizing material layer A, enhanced layer, sizing material layer B and close binder. The close binder can be bond closely with the structural layer of a building and set with particle layer. The invention discloses the constructing methods of pre-laying method and wet-laying method of this coiled material, where the pre-laying method can eliminate the procedure of laying protective layer in traditional construction and the wet-laying method can eliminate the procedure of making primary level making layer and has a few requirements for base level and can make waterproof construction. With respect to the existing techniques, it has the characters of simple structure, good waterproofing effect, strong anti-piercing ability, convenient use and maintenance, simple constructing method, etc.

Description

technical field [0001] The invention relates to a waterproof coiled material for building waterproofing and a construction method for building waterproofing, in particular to a composite waterproof coiled material and a construction method using the waterproof coiled material. technical background [0002] At present, the commonly used waterproof materials in China include modified asphalt coils, EPDM coils, PVC coils, coatings, etc. The construction process used is generally a pre-paving construction method, specifically: a. laying the base layer; b. base leveling layer; c. coating the base layer with a scraping base treatment agent; d. waterproof layer (coil or coating); , Fine stone concrete protective layer; f, binding steel bars; g, pouring concrete. [0003] These existing materials face the following difficulties in the construction process: [0004] 1) A few centimeters thick concrete protective layer must be poured before the main concrete is poured, which may cau...

AI Technical Summary

Problems solved by technology

[0004] 1) A few centimeters thick concrete protective layer must be poured before the main concrete is poured, which may cause invisible damage to the waterproof layer during the construction of the protective layer;

[0005] 2) During the construction of the main body of concrete, lifting and tying of steel bars, crossing of working surfaces and other activities may cause damage to the completed waterproof layer;

[0006] 3) The number of pre-paved waterproof coiled materials is huge, and the overlap of the coiled materials is prone to operational deviations, leaving hidden dangers of leakage, which in turn causes leakage;

Therefore, on the one hand, the steps of applying and scraping the base treatment agent and adding the protective layer increase the cost of the project; on the other hand, due to the strict requirements on the surface of the base, it will affect the construction period and construction cost

For example, during actual construction, it often occurs that the construction period is prolonged due to the wetness of the base surface.

In addition, the existing waterproof membranes need to use solvent-containing base treatment agents and adhesives during the construction process, and some hot-melt membranes also need to consume a lot of gasoline and other resources during the construction process, which is not environmentally friendly, but also a resource great waste of
